vibration isolation bearings

I just bought several sets of Rollerblock Jr's on this site. tweaks really are an area where there is no point buying new. They hay worked very well on every component I have tried

A friend of mine developed the small cups imbedded in the wood platforms. He gave the rights to FIM as their costs from Asia were so much lower. I have several of his platforms. I found the first Aurios were the best of the Aurios and were superior to these platforms. They are more trouble as your shelf has to be level. The newer less troublesome Aurios are much poorer as the indentation of the bass race is greater meaning that they move laterally only with greater force.

I never found Roller Blocks to be any good. I have a set with grade 3 balls that I never use.

Funny, I had precisely the opposite experience to TBG. I found Aurios pretty marginal, but Rollerblocks very good. Just shows how system dependent tweaks may be

David12, did you have the original Aurios. I did not like later versions.
